wireproto: advertise supported media types and compression formats

This commit introduces support for advertising a server's support for
media types and compression formats in accordance with the spec defined
in internals.wireproto.

The bulk of the new code is a helper function in wireproto.py to
obtain a prioritized list of compression engines available to the
wire protocol. While not utilized yet, we implement support
for obtaining the list of compression engines advertised by the
client.

The upcoming HTTP protocol enhancements are a bit lower-level than
existing tests (most existing tests are command centric). So,
this commit establishes a new test file that will be appropriate
for holding tests around the functionality of the HTTP protocol
itself.

Rounding out this change, `hg debuginstall` now prints compression
engines available to the server.

Failed qimport of patches from files should cleanup by recording successfully
imported patches in series file.
